[0027] Further, the upper die push plate 6 moves downward with the upper die base 2, and drives the lower die push plate 4 to slide inward along the guide groove 3 through the cooperation of the second inclined surface 5 and the first inclined surface 7, and then the side blade 10 moves along the guide groove 3. The guide block 8 slides in the direction of the cavity 22 , and at the same time, the product discharge plate 12 abuts against the upper end of the tubular product 23 under the action of the guide rod 19 and the spring 18 .
[0028] Further, when the groove 21 runs below the main cutting edge 20 along with the side cutting edge 10, the side cutting edge 10 punches off the inner wall of the tubular product 23 and supports the tubular product 23. The slag bag 24 of the tubular product 23 is punched out.
